Staple with parallel legs and two parallel cross pieces therebetween

Abstract

A staple with parallel legs and two parallel cross pieces therebetween comprising a pair of parallel legs, the legs being formed with upper ends and lower ends, the lower edges being bevelled to facilitate movement into the surface to which the staple is to be secured; an upper first cross piece formed as an integral extension of the legs and extending therebetween at the upper end of the legs; and an intermediate second lower cross piece positioned parallel with the first upper cross piece at a location intermediate the ends of the legs and integrally formed therebetween, the entire staple including its legs and its first cross piece and its second cross piece being integrally formed of a rigid material.

What is claimed as being new and desired to be protected by Letters Patent of the United States is as follows: 
     
       1. A new and improved staple with parallel legs and two parallel cross pieces therebetween comprising, in combination: a pair of substantially straight parallel legs, the legs being formed with upper ends and lower ends, the lower edges being bevelled to facilitate movement into the surface to which the staple is to be secured;   a substantially straight upper first cross piece formed as an integral extension of the legs and extending therebetween at the upper end of the legs; and   a substantially straight intermediate second lower cross piece positioned parallel with the first upper cross piece at a location intermediate the upper and lower ends of the legs and being integrally formed to each leg and permanently affixed thereto and extending the entire length therebetween, the entire staple including its legs and its first cross piece and its second cross piece being integrally formed of steel with the distance between the lower ends of the staple and the second cross piece being between about two and three times the distance between the first cross piece and the second cross piece and with the distance between the legs being between about two and three times the distance between the first cross piece and the second cross piece.   
     
     
       2. A staple with parallel legs and two parallel cross pieces therebetween comprising: a pair of substantially straight parallel legs, the legs being formed with upper ends and lower ends, the lower edges being bevelled to facilitate movement into the surface to which the staple is to be secured;   a substantially straight upper first cross piece formed as an integral extension of the legs and extending therebetween at the upper end of the legs; and   a substantially straight intermediate second lower cross piece positioned parallel with the first upper cross piece at a location intermediate the upper and lower ends of the legs and being integrally formed to each leg and permanently affixed thereto and extending the entire length therebetween, the entire staple including its legs and its first cross piece and its second cross piece being integrally formed of a rigid material.   
     
     
       3. The staple as set forth in claim 2 wherein the distance between the lower ends of the staple and the second cross piece is between two and three times the distance between the first cross piece and the second cross piece. 
     
     
       4. The staple as set forth in claim 2 wherein the distance between the legs being between about two and three times the distance between the first cross piece and the second cross piece.
